Answer:
I am not entirely sure what you are asking here but if I am right then the answer is -4(x-2) = 8 - 4x
Step-by-step explanation:
Multiplying binomials all you have to do is distribute the 4
Multiply -4 by x to get: -4x
Muliply -4 by -2 to get: 8 (Because two negatives make a positive)
Now you have -4x + 8
Rewrite so it flows better and the answer is:
8 - 4x

Recall that the standard form of a linear equation is Ax+By=C. Rewrite this equation in slope intercept form.
Answer:
y = \(\frac{-A}{B}\) x + \(\frac{C}{B}\)
y = 6/5 x + 9/5
Step-by-step explanation:
Ax + By = C Subtract Ax from both sides
Ax - Ax + By = -AX + C
By = -AX + C Divide both sides by B
y = \(\frac{-A}{B}\) x + \(\frac{C}{B}\)
-6x + 5y = 9 Add 6x to both sides
-6x + 6x + 5y = 6x + 9
5y = 6x + 9 Divide both sides by 5
y = 6/5 x + 9/5

Find that the radius of curvature of ^2y=x^3-a^3
at the point where the
curves cut the X-axis.
The radius of curvature of the curve \(a^{2y\)=x³-a³ at the point where the curve intersects the x-axis is 27\(a^{\frac{3}{2}\).
To find the radius of curvature of the curve \(a^{2y\)=x³-a³ at the point where the curve intersects the x-axis, we need to first find the equation of the curve and then determine the value of y and its derivative at that point.
When the curve intersects the x-axis, y=0. Therefore, we have:
a⁰ = x³ - a³
x³ = a³
x = a
Next, we need to find the derivative of y with respect to x:
dy/dx = -2x/(3a²√(x³-a³))
At the point where x=a and y=0, we have:
dy/dx = -2a/(3a²√(a³-a³)) = 0
Therefore, the radius of curvature is given by:
R = (1/|d²y/dx²|) = (1/|d/dx(dy/dx)|)
To find d/dx(dy/dx), we need to differentiate the expression for dy/dx with respect to x:
d/dx(dy/dx) = -2/(3a²(x³-a³\()^{\frac{3}{2}\)) + 4x²/(9a⁴(x³-a³\()^{\frac{1}{2}\))
At x=a, we have:
d/dx(dy/dx) = -2/(3a²(a³-a³\()^{\frac{3}{2}\)) + 4a²/(9a⁴(a³-a³\()^{\frac{1}{2}\)) = -2/27a³
Therefore, the radius of curvature is:
R = (1/|-2/27a³|) = 27\(a^{\frac{3}{2}\)

Whenever Jean sees the white streaks left in the sky by an airplane, she excitedly tells her kids it's Buzz Lightyear. One day, her son asked her how fast Buzz could fly. Jean, knowing that Buzz is really an airplane, told him about 500 miles per hour. How many feet per second can Buzz travel? Show your work, friends.
Answer:
The Buzz can travel 733.33 feet per second.
Step-by-step explanation:
An hour has 60 minutes, each of which has 60 seconds. So one hour has 60*60 = 3600 seconds.
The airplane can fly 500 miles per hour. Each mile has 5280 feet. So the plane can fly 500*5280 = 2640000 feet in one hour.
Per second, we have:
\(\frac{2640000}{3600} = 733.33\)
The Buzz can travel 733.33 feet per second.

What is experiment about?When if a relationship between two variables is said to be negative, it is one that does not just necessarily mean that the association is weak. Although though both variables tend to increase in reaction to one another, a weak positive correlation depicts that the relationship is not very strong.

Write the equation x2 + y2 + 6x + 8y + 24 = 0 in vertex form.
ANSWER
\((x+3)^2+(y+4)^2=1\)EXPLANATION
We want to write the equation of the circle in vertex form:
\(x^2+y^2+6x+8y+24=0\)The first step is to group the x terms and y terms together and take the constant to the right-hand side of the equality sign:
\(x^2+6x+y^2+8y=-24\)Now, complete the square for the x terms:
\(\begin{gathered} x^2+6x+(\frac{6}{2})^2+y^2+8y=-24+(\frac{6}{2})^2 \\ x^2+6x+9+y^2+8y=-24+9 \\ (x+3)^2+y^2+8y=-15 \end{gathered}\)Repeat the process for the y terms:
\(\begin{gathered} (x+3)^2+y^2+8y+(\frac{8}{2})^2=-15+(\frac{8}{2})^2 \\ (x+3)^2+y^2+8y+16=-15+16 \\ (x+3)^2+(y+4)^2=1 \end{gathered}\)That is the equation of the circle in vertex form.

For example, common multiples of 4 and 6 are 12, 24 and 36, but the lowest of those is 12; therefore, the lowest common multiple of 4 and 6 is 12.
Given:
4: 2 x 2

Camila has 6 bags of candy. She can pour 1/3 of a bag of candy into a bowl. How many bowls of candy can Camila make in all?
Answer:
18 Bowls of Candy
Step-by-step explanation:
Camila has 6 bags of candy, and she can pour 1/3 of a bag into a bowl. To determine how many bowls of candy she can make in total, we need to divide the total amount of candy by the amount of candy per bowl.
Since Camila can pour 1/3 of a bag into a bowl, it means she can make 3 bowls of candy with a full bag.
Now, we can calculate the total number of bowls of candy:
Total bowls of candy = (Number of bags) x (Bowls per bag)
Total bowls of candy = 6 bags x 3 bowls per bag
Total bowls of candy = 18 bowls
Therefore, Camila can make a total of 18 bowls of candy with her 6 bags of candy.

What is the base of a function?The base of an exponential function. If f(x) = ax, then we call a the base of the exponential function. The base must always be positive. Base 1. If f(x) is an exponential function whose base equals 1 – that is if f(x)=1x.
Given is a function, 2(4)ˣ+5, we need to find the base of the function,
With the multiplication of 4ˣ with 2, the rate at which f(x) changes is 2 times larger. Now it is added by 5, by adding 5 the value of f(x) is always 5 greater than the value of f(x).
This reverses the value of y for each corresponding value of x and increases the rate at which f(x) changes 8 times that of the original function.

What is the M.A.D. (mean absolute deviation) of the following data set?
8 9 9 7 8 6 9 8
The mean absolute deviation is 0.75
How to determine the mean absolute deviationTo calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set
From the information given, we have that the data set is;
8 9 9 7 8 6 9 8
Let's calculate the mean, we get;
Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8
Mean = 64 / 8
Divide the values
Mean = 8
Let's determine the absolute difference, we get;
Absolute differences=
|8 - 8| = 0
|9 - 8| = 1
|9 - 8| = 1
|7 - 8| = 1
|8 - 8| = 0
|6 - 8| = 2
|9 - 8| = 1
|8 - 8| = 0
Find the mean of the absolute differences:
Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8

Given:
The given function is y
\(y=x^3-4x^2+2x-1\)Find:
we have to find the equation of tangent line to the given curve at a = 2.
and then we have to draw the graph of the given curve and the tangent line.
Explanation:
(a) we know the derivative of any curve represents the slope of the tangent line to the curve,
Therefore, firstly we will find the derivative
\(\begin{gathered} y=x^3-4x^2+2x-1 \\ \frac{dy}{dx}=3x^2-8x+2 \\ at\text{ x =a= 2} \\ \frac{dy}{dx}=3(2)^2-8(2)+2=12-16+2=-2 \\ \end{gathered}\)Therefore, slope of the tangent line is m = -2.
Now, the equation of the tangent line to the given curve is
\(y=f^{\prime}(a)(x-a)+f(a)\)Now we have,
\(\begin{gathered} f(a-2)=(2)^3-4(2)^2+2(2)-1=8-16+4-1=-5 \\ and\text{ f'\lparen a\rparen=-2} \end{gathered}\)Therefore, the equation of tangent line is
y = -2(x-2) + (-5)
y = -2x+ 4 -5
y = -2x-1
(b) Now we will draw the graph of the given curve and tangent line to the given curve as follows
The graph of the curve is represented by blue colour and the graph of the tangent line is represented by green colour.
Arlene set up tables for a dinner. She put 10 chairs at each table. If t represents the number of tables Arlene set up, which equation could be used to find c, the number of chairs Arlene used?
Group of answer choices
c = 10t
t = 10c
t = c + 10
c = t + 10
Answer:
c = 10t
each table has 10 chairs, so for each table t, this gives you that number of chairs
Step-by-step explanation:
Answer: c = 10t (first answer choice)
=======================================
Explanation:
Let's say we had 1 table. This would mean we have 10 chairs.
Now let's say we had 2 tables. So we now have 2*10 = 20 chairs.
If we had 3 tables, then we have 3*10 = 30 chairs. And so on.
The rule is:
number of chairs = 10*(number of tables)
We can shorten that down to
c = 10*t
c is the number of chairs and t is the number of tables. The letters are placeholders for positive whole numbers. You can think of them as boxes where a number will go inside.

Answer:
a. False
b. True
c. True
d. True
e. False
Step-by-step explanation:
You want to know the truth value of various logical expressions when b = False, and x = 0.
And, OrAn And (&&) expression is true if and only if all parts are true. An OR (||) expression is true if any part is true.
When 'b' is false, b&&__ will be false, and !b||__ will be true. This makes (a) and (e) false, and (d) true.
When x = 0, __||x==0 will be true, so (b) is true.
The And (&&) of expression (c) will only be true when both parts are true. For b = False and x = 0, both parts are true, so (c) is true.
{a, b, c, d, e} = {False, True, True, True, False}
